A few nice ufo images I found:
UFO from Castle

The very unusual ‘UFO’ bridge in Bratislava.
Built by Doprastav and Hutni montaze Ostrava between 1967 and 1972 it is the longest cable-stayed bridge with just one pylon and is the only bridge in the list of the World Federation of Great Towers.
It is now a trendy restaurant.
